With Samuel's permission, I updated the packaging for the a11y components of GNOME 3.24 last month. I am not a DD yet so I will need sponsorship for these updates.
Now that Stretch is released, maybe now would be a good time to upload these to Debian? at-spi2-core at-spi2-atk atk1.0 (in pkg-gnome svn) Thanks, Jeremy Bicha
